JOSEPH HALL, OF `O'IISFIELD, MAINE.

WASHING-MACHINE.

Specification of Letters Patent No. 5,355, dated November 6, 1847.

To all whom t may concern:

Be it known that I, JOSEPH HALL, of Otisfield, in the county of Cumberland and State of Maine, have invented a new and useful Improvement on Machines for I/Vashing Clothes and Cleansing vCloths and other Fabrics, called the Concavo-Convex-Cylinder VashingMachineg and I do declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specicatio-n, in which- Figure l is a perspective view, Fig. 2 a longitudinal section; Fig. 3 a longitudinal view of fastenings; Fig. el a transverse section, and Fig. 5 a small roller for band and apron.

See drawings, annexed, where a, Figs. l, 2 and 4 represents the upper concavo-convex washing cylinder, and la, represents lthe lower washing cylinder both lying t-ransversely across the box.

b-Figs. l, and l represent the small iron crank, made fast to the small iron shaft, c, Fig. t, which passes through and is made fast to the upper wash-cylinder.

d, cZ-Figs. l, 2, and 3, represent two half elliptic steel springs on the upper edges of the sides of the box with ends resting on small metallic plates at s Figs. l, 2 and 3. These springs are connected with the lower fluted wash-cylinder by means of perpendicular movable slides, e, e, Fig. l. These slides have on the upper end a screw thread and pass through the springs lw, Fig. 3. On the upper end of each of the slides is a thumb-screw f f, to hold the springs to the slides and by turning to graduate the pressure. The slides have near their lower end at 0, Fig. 3, socket to receive the gudgeon of the lower wash-cylinders.

L b-Figs. l, 2, and 3, represent two wooden cleats; with sockets to receive gudgeons of small rollers.

Figs. l and 2, represents the apron passing over the small rollers, as at m, m, Fig. 2, between the two cylinders a and lc, and underneath the cylinder 7c. This apron is made of cot-ton drilling or other rm cloth the width of the box on the inside.

m, m, Fig. represent a transverse section of small roller.

g g, Fig. 5, represent the raised end of the small rollers to form drum for band edge of apron-see drawing hereunto annexed- Y j, Figs. l and 3 metallic plates for slides to pass through.

The construction and operation of this machine consists in having a tight box of proper size, as in Fig. A, say, four feet in length, eighteen inches in width, and twelve inches deep, made of pine boards, tight to hold the water and washing apparatus. Transversely across this box I place two concavo-convex or luted cylinders, about live inches in diameter from point to point of flutes, one near the top of the box with a small crank attached, as at b, Fig. t, and the other directly underneath and so as to mesh with the upper one. This lower cylinder is connected with t-Wo perpendicular slides running in grooves at the inside of the box with screw ends passing through the springs to which each is fastened by a nut as at f, Figs. 1, 2, and 3, by which nut the pressure is graduated. Near each end of the box I place a small roller, with raised or drum-ends for the apron to revolve over; and I make an apron of cotton drilling or other firm cloth ofthe width of the box on its inside, with about four inches of each serve as bands to run on the drum ends of the rollers. This apron is made to pass over the rollers, underneath the lower cylinder and between that and the upper cylinder and is made to revolve by means of the crank attached to the upper cylinder. Upon this apron the clothes and other materials to be washed are laid.

The principle of washing by the machine consists in crimping, rubbing and squeezing the clothes, whereby the cloth has its texture loosened; and is freed of its dirt by the pressure of the flutes into the volutes by which the water is forced 4out with the dirt. This operation I perform by means of the crank attached to the upper fluted cylinder, which causes the apron, upon which the clothes are laid, to revolve over the small rollers, and to pass between the luted cylinders, where they receive the crimping, rubbing and squeezing operation; and thence are carried to the opposite end of the box, where they are again saturated with water, and by a reversed motion of the crank are brought back and again made to pass beedge doubled over and stretched down to i tween the Wash-cylinders; and this operation is continued until the Washing and cleansing is completed.

This Washing apparatus, or machine, may 5 be adopted to the cleansing of cloths, Wool, rags, and other similar materials, and can be operated in boxes and vessels of various sizes and forms.

What I claim 4as my invention and desire belt and luted rollers, substantially in the manner described, and` I disclaim as my invention the box containing the Washing apparatus, and every thing in the construction of this machine except what I have specied in my claim.
